it powered delivery, met the wattage claims and good at meeting the surge wattage, like when the refrigerator, anything with a motor when it turns on and off and cycle the, you got a surge. this met it perfectly. also smooth power. >> rick: 7,000 watts. >> arthel: $900. >> $900. that's the beginning because what you really want to do is get a transfer switch. that's about another five to 900 installed, but that let's you actually hook it as you did right up to your home's electrical system. >> arthel: but a professional has to do that? >> rick: i didn't do it myself. >> yes, but at least you had it done and at that point you're powering the house instead of running extension cords. >> rick: you have to bring somebody in, a professional to install that. then you can decide what you want to power up and what you want to not. you're not going to be doing laundry or something on your generator, or maybe you are. >> you can if you go for this, a 10,000 watt generator, you can. in summer you can power a whole house, air conditioner, yes. but with these 7,000 watt units, they power most things.
